 note = {This paper describes a proposal of noncontact positioning system using pinning effect of superconductor. The proposed system consists of a superconductor, electromagnets, and actuators. The levitation force is obtained from the pinning force between a superconductor and an electromagnet and is controlled by a current switch. The pinning of electromagnet is not used for only levitation, but hold the position of the levitated object. The positioning system is moving like an inchworm system. A prototype of proposed system is introduced and some experimental results are shown. These results verify the feasibility of the proposed noncontact positioning system., Asia-Pacific Symposium on Applied Electromagnetics and Mechanics (APSAEM08)},
